/**

 * The server-side virtual channel API follows the Microsoft Remote Desktop

 * Services API functions WTSVirtualChannel* defined in:

 * http://msdn.microsoft.com/en-us/library/windows/desktop/aa383464.aspx

 *

 * Difference between the MS API are documented in this header. All functions

 * are implemented in and integrated with libfreerdp-channels.

 *

 * Unlike MS API, all functions except WTSVirtualChannelOpenEx in this

 * implementation are thread-safe.
